[QUOTE="ionbeam, post: 1136230, member: 277"] My engine sat for about 6 weeks before it was opened up, by that time all my cylinders had the mystery orange fuzz too. Hmm, aluminum engine and specially coated cylinder sleeves, what is there to rust orange? Aluminum rusts (oxidizes) white. When I wrote to the Forum about my orange fur lined engine the best guess was that it was fuel related. Moisture gets in through open valves. In the case of my engine 12 valves were open all at once. Ouch. [/QUOTE]
